Quad4 - Four Piston Actuator

Brand: SVF Flow Controls, LLC

The SVF “Quad4™” quarter-turn rack & pinion actuator is a four piston actuator which generates torque around a centrally located pinion, giving more than double the torque of single & double rack & pinion actuator designs.

The increased number of pistons allows their diameter to be reduced while maintaining its high torque, allowing the reduced size of the actuator
